● In this regard, observe the relevant chapters in the documentation associated with the
components of the complete drive system.
● Repair any damage that occurred on the machine/motor spindle.
Note
When operating the motor spindle with a converter, refer also to the Operating
Instructions of the frequency converter if electrical faults occur.
Table 9- 1 Key to causes of faults and remedial measures
No.
Causes of fault
Remedial measures
A Overload Reduce load
B Interruption of a phase in the supply ca-
ble
Check frequency converters, feeder cables and contactors, if necessary
C Interruption of a phase in the supply after
switching on
Check frequency converters, feeder cables and contactors, if necessary
D Converter output voltage too high, fre-
quency too low
Check the settings on the frequency converter, perform automatic motor
identification
E
Stator winding incorrectly connected
Check the winding circuit and, if applicable, the wiring of the contactors
F Winding short circuit or phase short cir-
cuit in stator winding
Measure the winding resistances and insulation resistances, repair after
consultation with manufacturer
G
Cooling water not connected/switched off
Check cooling water connection/switch on cooling water
Water connection / pipes defective
Locate leaks and seal as necessary, or consult the manufacturer
H
Cooling water flow rate too low
Increase cooling water flow rate
Inlet temperature too high
Set correct inlet temperature
I Heat dissipation impeded by deposits Clean the surface of the drives and ensure that the cooling air can flow
in and out unimpeded
Cooling air inlet/outlet is blocked by for-
eign bodies
Remove the blockage and ensure that the cooling air can flow in and
out unimpeded
J Insufficient shielding for motor and/or
encoder cable
Check the shielding and grounding
K
Excessive drive controller gain
Adjust the controller
L
Rotating parts are grinding
Determine cause and adjust parts concerned
Foreign bodies within the motor
Repair by manufacturer
Bearing damage
Repair by manufacturer
M
Rotor not balanced
Decouple rotor and rebalance
N
Rotor out of round, shaft bent
Please consult the manufacturer
O
Poor alignment
Align machine set, check coupling
P Cooling water pipes/water connection
defective
Locate leaks and seal as necessary, or consult the manufacturer
